I'm afraid I still don't understand. Be a bit more expansive. We can't guess and it's not obvious from your script exactly what you want to do.
I'm not being critical ... I'm just trying to understand.
Here's a description of what's happening at the moment.
I don't know what the file name of the page below is ... so I'll assume it's main.php for the following ...
<?
// You set up [B]two[/B] variables that don't get used
// later in the script
$news = "www2.truman.edu/~d1514/news.php";
$index = "www2.truman.edu/~d1514/index.php";
$index ="www2.truman.edu/~d1514/about.php"; // index again??
// Using $_GET implies that three values, {news, index, about}
// have been sent to this page, usually by a form, but could be a
// link ... href='main.php?news=blah1&index=blah2&about=blah3'
// Then, the following lines ...
include $_GET['news'];
include $_GET['index'];
include $_GET['about'];
// ... would actually be doing ...
// include 'blah1';
// include 'blah2';
// include 'blah3';
?>

<!-- Here you have three links to pages that don't relate to anything above. -->
<a href = 'news.php'>Stories</a><br>
<a href = 'index.php3'>Home</a><br>
<a href = 'about.php'>About Me</a><br>
